Abstract : The AGGIE Monte Carlo code was used to provide data on the leakage of photons from the six sides of a Boundary Layer Illumination Radiation Model (BLIRB) space containing one or more clouds. The leakage data are to be used to evaluate the results of similar calculations by BLIRB. The data to be generated by the AGGIE code were for three scenarios. Scenario 1 defined a simple 3-D BLIRB space. The region outside of the BLIRB space was treated as a vacuum in each of the scenarios. The second scenario simulates the shadowing effect one cloud has on another cloud. The third scenario defines a waffle geometry in which the scattering medium is squashed in one direction, resulting in an aspect ratio of 10:1. The AGGIE results, giving the fraction of the incident photons that leak out of each of the six sides of the BLIRB space for each scenario, are listed in tables and plotted in figures, where they are compared with simular calculations by the BLIRB code.
